The respective values for the above examples are:
−15.2 V
188.3 mA, 442 Hz
1.23 V, 2.34 V, 60 Hz
1.924 MΩ
15.2 V, 188.3 mA, 442 Hz
25.86 dBm, 442 Hz (25.86 dBm = 15.2 V at 600 Ω)
104.3 °C
219.74 °F (same value as 104.3 °C, in Fahrenheit)
4.274 mV (same value as 104.3 °C for a K-type thermocouple, in volts)
140.135 Ω (same value as 104.3 °C for a pt385 RTD, in ohms)
The primary and secondary units are: V, DBM, A, OHM, F, CEL, FAR. The units for the
<frequency value> is always assumed to be Hz.

(Output Error query) Returns the UUT error and units computed by the Calibrator after
shifting the output with the INCR command. The return units are PPM (parts per
million), PCT (percent), DB (decibels) or 0 if there is no error. The UUT error is not
computed when editing frequency.
Response: <value of error>,<units>
Example: OUT_ERR? returns −1.00000E+01,PCT
Returns −10% when the UUT is reading low by 10%.

(Phase Difference command) Sets a phase difference between the Calibrator front panel
NORMAL and AUX or 20A terminals for ac power and ac dual voltage outputs. The
NORMAL terminal output is the phase reference. The set range is 0.00 to ±180.00
degrees, with + for a leading phase difference and − for a lagging phase difference.
Parameter:
<phase value> DEG
(DEG, for degree, is optional)
Example: PHASE −60 DEG
Set the phase difference so the frequency output at the AUX terminals lags the frequency
output at the NORMAL terminals by 60 degrees.
